Today I lost my ability to make phone calls or do anything with my phone away from WIFI.
If I tried to make a phone call, I'd get a "Not Registered to Network" error message.
I can still do WIFI calling but nothing else away from WIFI connection.
I then went into network settings and chose "manual" for network operators. I was able to restore texting and calling. But I have no data. The options that I see from the scan after choosing "choose network operators manually" are 3-5 choices and they all read "Home". Some of these options give me error messages and others gives "Registered to network" - which then lets me call and text message.
So far I have tried rebooting. Taking out the sim tray and placing the sim card back in. I have tried resetting network settings. I have tried resetting APN to default.
Anyone know of a fix for this Samsung message occurring on the A70?
I am trying to do what I can to avoid resetting to factory defaults.
Thanks.
Others things I have tried:
Placing sim card in the other tray.
Making sure my sim card works in another phone. (It does.)
I fixed the issue.
Restoring APN to defaults or resetting APN, does NOT work, apparently.
I had to manually create and save an APN and enter the appropriate data, as instructed by my carrier's website.
The key data entry was probably adding a website (fake example: "t-mobile.com") to the "APN" entry, which was blank in the default APN that my Samsung was using. I wonder what happened there.

Last week an earthquake has occured at Istanbul (5.8) and all the gsm carriers stopped working for hours at whole country. That was interesting. And when you tried to call someone, phone were showing a dialog which was shown to you. And also as you said, peole had to use wifi to call someone via WhatsApp etc.
So, I think the problem you lived may be your gsm carrier's issue and probably they fixed it while you were trying to fix it yourself.

No. The notion of an outage of service occurred to me but ultimately the fact was my sim card worked just fine in my other phone.
The problem and fix had everything to do with the APN file. I'm just wondering why that APN would change all of sudden.
What I've read about Samsung phones is that this "Not registered to network" is a common problem.
I hope this thread will be useful to someone in the future.

Hello!
This morning I suddenly began getting a failed message any time I attempted to send an SMS message. There doesn't appear to be any error code or anything, just an exclamation point next to the message which triggers a new attempt if i touch it.
I assumed it was a passing network error and ignored it for awhile. During my last break at work I realized that still could not send SMS, so I powered my phone off and back on to no avail. I called AT&T tech support, thinking it may have been a provisioning or switch error, they sent me an SMS which came through fine, and I sent a few test SMS while on the line with them which also went through perfectly.
After getting off of the phone with AT&T I discovered my SMS was not working again. Messing around with it later I learned that I can send and receive SMS normally while on a call, and can send MMS messages regardless, but am unable to receive MMS unless I'm on a call. Data is working fine (both AT&T and WiFi) and I can make and receive calls normally.
When I got home from work I called AT&T again. They had no suggestions, but told me they could not help me troubleshoot while I was on the phone needing troubleshooting (which makes perfect sense, but was the only phone available at the time.)
I have since re-flashed my phone to the official factory rom and done a reset to factory settings/deleted all data by following this tutorial here: (XDA won't allow me to link the video, but youtube user appdroid seven, video title "How To Unroot & Factory Reset At&t Samsung Galaxy S III I747", I fouind the video in the thread titled "[ReF} ALL IN ONE NOOBS VIDEO* GUIDES TO ROOT | FLASH | & MORE [Mods this goes in ATT]" post four.)
I am still having the same issue, but am running out of ideas on how to fix it... any help would be greatly appreciated.
I had the same problem. I just figured out how to fix it. Worked on my friends phone too. Both S3s.
I found the below on another site.
1) With phone on, take off back cover and press your SIM card so it releases from the spring. It won't come all the way out as it's blocked by the battery. This seems fine - I didn't bother trying to force it out as I didn't want to break anything...
2) Once you see the message that the SIM card is removed, go to the dialer and dial *#2263#
3) You should see a menu with band selections. The current setting is "Automatic". If you switch to "GSM All", you will be EDGE (2G). If you switch to "WCDMA All", you will be on HSPA+ (3G, though AT&T and others call it 4G).
4) Press the SIM card back into place until it clicks. For whatever reason the phone will not recognize it until you reboot. Upon reboot you should see your new setting in effect.
I switched to WCDMA ALL... then rebooted. This put it on HSPA only. Then I did the above again and selected automatic and rebooted. LTE came back online and the SMS worked again. No problems since. Hope this helps.

I just got this problem after the AT&T update got pushed to my phone yesterday. I followed the steps above, trying to text between each switch of the radios. I found that I could text on "WCDMA All" but not "LTE All". Going to "Automatic" gave me LTE radio back, but MMS/SMS failed to work. However, text did work if I was on a phone call! This got me thinking about the APN settings and whether they were right. Sure enough, AT&T messed with "APN type" on the latest upgrade. It should read "default, mms, supl, hipri" but instead read "default, mms, supl". I created a new APN with the correct APN type, reset the radio to "Automatic" as per the instructions above, and rebooted. I now have LTE and MMS/SMS back!
I hope that this helps!
Now, how do I go about billing AT&T for my lost time?
Hey guys, just unwrapped my new N5x and popped in my sim card. Yet for some reason I can't make or receive any calls!
Calls to me go straight to voicemail, and when making an outgoing call it either immediately says call ended or after a while says network unavailable.
The strange thing is that the entire time I'm connected to LTE (full bars) and data works fine (I can use chrome), and I can even send and receive SMS!
It's been like this straight out of the box. I reset the network settings, then factory reset the device, then upgraded to 6.0.1, rinsed and repeated with no luck.
Probably related: I tried setting the phone from LTE preferred to 3G or 2G but it still says connected to LTE. Even did it manually from the *#*#4636#*#* and nothing changed.
I'm using HOT Mobile in Israel and the American version of the phone. All bands are here are supported.
Any thoughts on how to proceed?
Do US specifc models of phones normally work fine in Israel?
I know I had these symptoms when I managed to accidentally swap my UK model to use USA bands. Only potential difference is that I don't think SMS worked for me.
If someone more knowledgeable knows where the "Network settings reset" pulls values from and to, that might help.
Or which partition holds the data that makes a US phone a US version and an EU phone an EU version (assuming it isn't hardware), we could potentially flash stuff.
Yeah they do. I have a friend with a 5x and his phone is working fine. :/
Check your apn settings, re add them again to test.
Maybe your network do not support lte calls, try it on 3g. This was my solution even thought my network supported volte and worked on s6 but not on my 5x.
I see you tried the 3g option, my problem was another app causing the conflict between lte and 3g. Able to source for another spare sim to try?
I deleted the apn settings - no luck. tried 2 different service providers and same results with both
I havnt installed anything yet and wiped the phone to be sure. Could a stock app be causing the conflict? How can I check?
did you try having your friend put his sim in your phone and yours in his to see if it works?
Yep - he's on the same service provider that I am. Didn't work. Also tried a Sim card from a different service provider.
Here is a solution if you still need it http://forum.xda-developers.com/showpost.php?p=64023143&postcount=10
Hi - Never done this before, but I am having problems with MMS using my G8 (LM-G820UM) and hoping someone out there might be able to help. You will have my eternal gratitude. At this point, I would even consider rooting if you think that would help.
The current issue: I mistakenly bought a US/Sprint phone and am in Canada. It appears that cross-flashing on a G8 is verboten, so that's not an option (please correct me if I am wrong - the threads I have read seem to be several months old). Everything seems to work properly, no problem with voice, Internet, and SMS... but I cannot send or receive MMS. My APN appears fine... though I cannot edit it. But here is what makes me scratch my head:
Available network modes are Automatic (what I use), LTE/CDMA, CDMA, GSM/UMTS. If I switch to LTE/CDMA then MMS works fine, but SMS and voice disappear.
So... the solution I've come up with, which *sucks*, is to swap network modes whenever I want to send or receive MMS... which isn't very often, but does come up once a week or so.
I have tried changing to each of the "Preferred Network Type" options within ##4636##, but none of these worked for both SMS and MMS at the same time.
Reading the forums, I found a solution involving ##3282# and performing a "reset"... which appeared promising... but there does not appear to be an edit or reset option when I enter the menu.
Thank you!!
And also... live and learn... one more thing to check/test when I buy a used phone...
You can use google messages it works perfect mms i have a sprint g8 also on movistar carrier from mexico.and i use google messages for the same reason.

I've had the exact same problem, and the reset option within the ##3282# menu is definitely the solution. You have to go to apn settings, view, 3 buttons at top right, and reset. If you had the right sim in of course, mms should now work

You are a lifesaver! Yes, that was what I was missing - now everything appears to be working as expected. I believe it was your post in another thread that started me down this path as well, thank you for bringing it full-circle.
I can't seem to call anyone from my contacts or otherwise. I just get a call ended prompt as soon as I call someone.
It doesn't happen when the caller on the other end is with the same network operator as I. Also, the helpline number for my operator when called, tells me that the number doesn't exist dumbfounded to say the least.
I am on the global 12.5.2.0 (RKHMIXM) ROM.
All worked well till yesterday btw.
I have tried the following:
1. Changing network preferences from 2g all the way to 5g.
2. Clearing all data on Phone and Phone services via app settings.
3. Tried calling with wi-fi off.
4. Tried calling with cellular data off.
5. Tried going into airplane mode and reconnecting to my network operator.
6. Rebooting the phone.
7. Turning off the phone and then restarting.
Any help would be highly appreciated.
Thank you.
Regards,
SAN
Have you done any portability application to another network with the same number maybe? It's probably your network provider and not the phone. Of course you can factory reset and check again.
Call them again so you speak with another representative and check again your number and maybe reset its network settings.
Finally what will solve it for sure is to contact them and disconnect the number and then reconnect it but this is complicated.

I don't want to factory reset tbh, I will lose all my app settings and security camera settings, it's a pita setting those up.
No to portability from another network. I will try calling them from a landline tomorrow and if not try getting a new SIM card since mine is pretty old.
if google phone dialer settings assisted dialing make sure correct country is displayed if it is turn it off and try placing a call then it should work and then you can re-enable it.

Second update. It resolved itself. Started today and got resolved by itself.
So I am definitely thinking it was a network issue after all. Thank you for your prompt response, highly appreciated.

It was on. Shows detect automatically but doesn't show the name of my country. But it seems to have been an operator issue at their back end. Resolved itself.
My new Pixel 6 Pro keeps having NO SERVICE. Restart required to temporarily resolve. - Google Pixel Community
Anyone else from the community having this issue and manage to resolve it ?
Happens in all different region.

Had the same on my wife's P6. The connection would appear briefly, the call sometimes would go through but then connection lost and asked to switch off plane mode by the system. Tried 3 different sim cards, hard reset etc.
Filed a return and her new phone is working as it should now.
That sux, as mentioned an RMA may be needed...
Started happening to me when I updated to v37. It was fine until then. I'll probably flash the old radio image later on tonight.
Edit: nvm, the radio.img is the same between 36 and 37. It is odd that this just started happening in the last 24-48h.

Your wife is lucky.
I've read on the link i posted that a guy rma 3 time with the same issue ....
If someone figures out a fix, please let me know. I am getting desperate here.
Been eyeballing the device ...from LTE to No Service..back to H+ than picking up signal again rotating for about 4-10 mins
Now I'm testing out turning off adaptive connectivity under network and internet sitting inside my office now.
Fixed on my end.
Settings> Network and Internet> Setting bolt icon next to my mobile carrier (T-Mobile)> Access Point Name> Created my own with the same settings from my carrier (T-Mobile) but with "APN type" only having: default,supl,mms,DUN
The rest of the APN stuff seemed to break my mobile data.
Hope this works for others too.

Interesting. Did you contact T-Mobile or Google and asked about this?
This seems like the type of issue that should be easy to replicate.
I would suggest to contact Google either way, since your phone might have a hardware issue (partially defect antenna or whatever) and you need to sort this out, before you run out of warranty and get problems later down the road (fix not working anymore).

So do you mean go into SIM card network page where you can see APN volte etc....under APN and create a new APN but with the exact same setting from the carrier ?

This worked for me. Thanks bro!
I started by turning off 2G. Worked for about 3 or so days. Then the issue came back. So, I turned off WiFi calling because I read somewhere that it was causing issues. I haven't had the problem since. It's only been a few days though. FYI I'm on Verizon.
I'm pretty sure it's yet another bug on the long list of them on this phone..
Go into settings > Network and internet > Sims click your provider there scroll down to Preferred network type change to LTE. I figured this out on my wife's phone. You'll loose 5g but it'll get you by temporarily until you figure out a better solution.
